Download or read book The REXX Language on TSO written by Gabriel F.. Gargiulo and published by CreateSpace. This book was released on 2012-08-19 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will teach you how to write programs in the REXX language on IBM mainframe computers. It is useful for technical, applications, and maintenance programmers working on new or legacy code written in the REXX language. It describes the REXX programming language for TSO, MVS, OS/390 and Z/OS. (IBM mainframe operating system environments). The book quickly gets you writing programs in REXX. It covers all REXX language elements, all REXX built-in functions, and the more important TSO-only functions. You will find URLs in the book linking to a set of practice problems on a public webpage, as well as additional information on setting up your TSO session to execute REXX programs. This book was written and published in 2012 by the author of "REXX in the TSO Environment." The REXX Language on TSO improves on "REXX in the TSO Environment" in every way: it clarifies important points; it is better organized, and gives better examples. REXX is a high-level scripting language created in the 1980's by IBM for the IBM mainframe operating systems CMS and MVS. It quickly gained popularity and expanded into other environments such as Netview, CICS, AIX, QMF, VSE and OS/2. REXX is often used for prototyping applications, front-ending operating system commands and TSO/ISPF panel applications. Its flexibility and clear straightforward syntax makes it a welcome replacement for IBM utility programs. REXX is generally not used for high-volume business applications because of its performance limitations with respect to compiled or assembled languages. REXX is able to read and write sequential files and/or PDS members. It contains all programming language features, including the ability to do calculations with decimal numbers to any precision. It is especially useful in manipulating character strings in free-column format. There is a chapter containing examples of REXX programs, macros, and user-written functions. Explanations of the code are shown on the facing page.

Download or read book Practical Usage of TSO REXX written by Anthony S. Rudd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: REXX is a general purpose language which is easy to learn. It contains an extensive library of powerful functions which greatly reduces the amount of coding necessary to write applications. The use of REXX in a wide range of environments simplifies the writing of applications to run under different hardware and operating systems, and its expansibility allows other components to make sure of REXX facilities and vice versa. Practical Usage of TSO REXX provides a concise source of information for the development and implication of applications using the REXX language. The author adopts a practical approach, using lists and diagrams to illustrate relevant points. This third edition, (previously titled Practical Usage of MVS REXX), has been revised to include the new REXX features introduced for the OS/390 TSO/E environment.

Download or read book The Rexx Language on Tso written by Gabriel F. Gargiulo and published by Createspace Independent Pub. This book was released on 2013-07-13 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The REXX programming language includes built-in functions that simplify programming. REXX Functions let you manipulate data strings or do mathematics simply with a minimum of programming effort. This book explains 72 REXX functions that you can use in your REXX programs. This book is about TSO REXX functions, but we have included a few that work in CMS only. A function is a built-in feature of the REXX language. Functions are always available to you when you are writing your program. They provide an easy way to manipulate data strings or to perform arithmetic on numbers. Using functions simplifies programming and provides reliability, because the functions were created and tested by the software manufacturer (IBM.)The Index is not like most indexes that list only language features alphabetically. They are no help if you don't know the name of the language feature. This index shows the common English language name for a feature, for example, "Convert decimal number" points you to the REXX equivalent D2C. You don't have to know that D2C means "Convert decimal number to character" in order to use the index.The examples are simple and clear and will show you the different ways to invoke, or use REXX functions in a REXX program.To aid you in finding the function that you need, one chapter is devoted to listing the functions, classified by what they do. Each of the built-in functions is shown in detail with examples of use. The functions are shown alphabetically.As a bonus, I've included several supplementary chapters to make life easier for the REXX programmer:1. How to write REXX macros.2. Compatibility Issues across platforms.3. Precedence of Operators. What REXX processes first, in complex expressions?4. How to execute TSO Commands, in Native Mode (Ready Mode) TSO, in ISPF Option 6, on the command line on ISPF panels, and in batch.5. How to specify Dataset names in TSO commands. An explanation of TSO naming conventions.6. Finally, the TSO commands that you are likely to use in your REXX programs, arranged by their function, with clear and simple examples.

Download or read book Implementing REXX Support in SDSF written by Lydia Parziale and published by IBM Redbooks. This book was released on 2007-06-26 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Restructured Extended Executor (REXX) language is a procedural language that allows you to write programs and algorithms in a clear and structural way. It is an interpreted and compiled language, and you do not have to compile a REXX command list before executing it. With IBM z/OS V1.9, you can harness the versatility of REXX to interface and interact with the power of SDSF. A new function called REXX with SDSF is available that provides access to SDSF functions through the use of the REXX programming language. This REXX support provides a simple and powerful alternative to using SDSF batch. This IBM Redbooks publication describes the new support and provides sample REXX execs that exploit the new function and that perform real-world tasks related to operations, systems programming, system administration, and automation. This book complements the SDSF documentation, which is primarily reference information. The audience for this book includes operations support, system programmers, automation support, and anyone with a desire to access SDSF using a REXX interface.

Download or read book TSO CList to TSO REXX Conversion Handbook written by Gabriel Gargiulo and published by CreateSpace. This book was released on 2015-05-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for the programmer who needs to convert a program written in TSO-CLIST to TSO-REXX in the z/OS TSO/ISPF environment. You need some familiarity with both languages in order to do a conversion. This book will show the correspondences, or lack of them, between CLIST language features and REXX language features. CLIST language features are shown on the left-hand page, with the corresponding REXX language feature on the facing, right-hand page.TSO-CLIST dates back to the beginning of TSO in 1971. It truly is a legacy language. IBM continues to support it, and even enhance it, because so many of its customers have active, functioning CLIST programs in use.CLIST language is found only in one environment, the z/OS TSO/ISPF environment. Experience programming with CLIST is not readily transferable to any other environment. The REXX language is found mostly in the z/OS TSO/ISPF environment, and in QMF, CICS, DOS/VSE, and Netview. Knowing REXX makes you more valuable to your employer.The number of programmers who can understand CLIST language is diminishing. It is a good business decision to convert CLIST programs, where possible, to REXX programs. I'm sure most programmers will remember the nightmare of having to fix a program that is so old that no one left alive knows what the program is expected to do.

Available in PDF, EPUB and Kindle. Book excerpt: This IBM® Redbooks® publication is based on the book Introduction to the New Mainframe: z/OS Basics, SG24-6366, which was produced by the International Technical Support Organization (ITSO), Poughkeepsie Center. It provides students of information systems technology with the background knowledge and skills necessary to begin using the basic facilities of a mainframe computer. For optimal learning, students are assumed to have successfully completed an introductory course in computer system concepts, such as computer organization and architecture, operating systems, data management, or data communications. They should also have successfully completed courses in one or more programming languages, and be PC literate. This textbook can also be used as a prerequisite for courses in advanced topics, or for internships and special studies. It is not intended to be a complete text covering all aspects of mainframe operation. It is also not a reference book that discusses every feature and option of the mainframe facilities. Others who can benefit from this course include experienced data processing professionals who have worked with non-mainframe platforms, or who are familiar with some aspects of the mainframe but want to become knowledgeable with other facilities and benefits of the mainframe environment. As we go through this course, we suggest that the instructor alternate between text, lecture, discussions, and hands-on exercises. Many of the exercises are cumulative, and are designed to show the student how to design and implement the topic presented. The instructor-led discussions and hands-on exercises are an integral part of the course, and can include topics not covered in this textbook. In this course, we use simplified examples and focus mainly on basic system functions. Hands-on exercises are provided throughout the course to help students explore the mainframe style of computing. At the end of this course, you will be familiar with the following information: Basic concepts of the mainframe, including its usage and architecture Fundamentals of IBM z/VSE® (VSE), an IBM zTM Systems entry mainframe operating system (OS) An understanding of mainframe workloads and the major middleware applications in use on mainframes today The basis for subsequent course work in more advanced, specialized areas of z/VSE, such as system administration or application programming
